While watching movies and series there is an blinking symbol in the upper right corner of the screen. It’s working on my nerves. So I like to know what it is and if I can disable it.
Would you happen to have a screenshot/short movie ?
It might be under-voltage warning indicator, suggesting your power supply is not powerful enough.
It used to be rainbow square, they have hanged it to something else afair.
if its a yellow square its high temperature and a throttled CPU
If its red its a dangerous high temperature
If its more rainbow like your power supply isn´t giving the necessary amps so you should try a better usb charger
